Python3.11 seems to break venv created from non-system python with zipped stdlib

I think 3.12-only change is OK. Since we’re already build python from source, we can workaround this with a patch in 3.11.

For the change, I did a test. First I changed the zip file path calculation to this:

    if prefix:
        pythonpath.append(joinpath(prefix, ZIP_LANDMARK))
    else:
        pythonpath.append(joinpath(PREFIX, ZIP_LANDMARK))

Then, two test cases will fail. test_embed and test_getpath.

Then I tried simply removing the venv condition like this:

    # Then add the default zip file
    if os_name == 'nt':
        # QUIRK: Windows uses the library directory rather than the prefix
        if library:
            library_dir = dirname(library)
        else:
            library_dir = executable_dir
        pythonpath.append(joinpath(library_dir, ZIP_LANDMARK))
    elif build_prefix:
        # QUIRK: POSIX uses the default prefix when in the build directory
        pythonpath.append(joinpath(PREFIX, ZIP_LANDMARK))
    else:
        pythonpath.append(joinpath(prefix, ZIP_LANDMARK))

now all tests passed. This may be the simplest change?
